Texas Instruments - Smart high-side switches for 12V automotive system usage

发布日期: 2019-04-04
Texas Instruments TPS1HA08-Q1 intelligent high-end switch provides powerful protection and diagnostic functions designed for use in 12V automotive systems. The device prevents faults by a reliable current limit, which depends on the device model and provides 80A and 20A currents. The current limit can be configured to react to an overcurrent event by immediately closing the switch or adjusting the output current at the set point. The high current limit option allows use in loads that require large transient currents. The low current limit option provides better protection for loads that do not require high peak currents. The device also allows high-precision analog current sensing, which provides improved diagnostics when driving loads. The device can provide predictive maintenance and load diagnostics by reporting load current, device temperature, and supply voltage to the system MCU, thereby extending system life. These devices meet the automotive application requirements of AEC-Q100.
